SteriPEN Adventurer Opti

Have utilized the SteriPEN Aventurer Opti now on several outings this summer instead of my pump water filter systems and found it to be very simple and effective. On previous trips (before the SteriPEN), after a rain, the rivers and streams would be full of silt and dirt. That fine silt clogged my pump filtration systems. I tried different pump systems. I replaced filters. I backwashed the units. I found that back washing the unit once for every liter of water, no matter what pump system I was using,… Full review

SteriPEN Adventurer Opti

I have this and love it. I love it; it works well. But like any new gadget it does take a few times to get the hang of it. Granted the cost of the battery is a little pricey, but you should be able to use it a year on a set of batteries. So that's not really a big deal, not like I would ever use 6,000 gallons of water hiking in a year. It's a good packable size. I bought this because most methods of water purification is just awful tasting and the the thought of me drinking bleach water is just… Full review

MSR SweetWater Purifier System

Great little pump. I've had mine must be almost 10 years or pretty close. Bought the system when they first came out, used in all four seasons, used it to get water from a streams, lakes, through the ice. Works really well. Replacement filter is a little pricey, and it doesn't pump the volume of the newer ones ,or as fast. But I just don't have the heart to replace it. It works so well and the Sweetwater purifier solution that comes with it makes the water taste like the water that comes out of… Full review

SteriPEN Classic

I got this three summers ago after going on a backpacking trip with a buddy who had one. I really like the convenience and the quickness on how it works. Here in CO most of the mountain streams we come across run clear so we are not dealing with murky, dirty water. The included filter works well to block the bigger stuff. I've put three years of use on the Classic model and to date, have had zero issues with it. I buy the lithium ion batteries for it and the last set made it through the complete… Full review

SteriPEN Sidewinder

Works well but is better suited for base camp or cabin use rather than backpacking. This is my third Steripen, I also use an Adventurer and a Classic. I originally bought this because it did not require any batteries which would be one less thing to worry about. As far as basic operation goes they all work the same. I got this Sidewinder about 6 months ago and in that time I have had no issues or problems with it at all. It works just as the manufacturer says and since I have not acquired any… Full review

SteriPEN Traveler

This water purifying source is very easy to use. It is very small and lightweight for backpacking trips. I recommend a backup treatment option of some kind in case you run into battery or workmanship issues. At right around $50 it is very affordable. My friend had a SteriPen Classic and the quick, easy treatment of the water with the UV light was very impressive. I found this smaller, lighter model and purchased it instead. It provided about 400 treatments before I had issues with it (the light… Full review

First Need Deluxe Water Purifier XL

Quick and easy to use, back flush, and clean. Very high quality. A bit heavy compared to other filters, but the peace of mind it gives is worth the extra few ounces. This purifier gives me the peace of mind knowing my water source will not make me sick. It is effective against bacteria, cysts, and viruses plus it removes giardia and cryptosporidia while using no chemicals to treat the water. The purifier removes chemical contaminants and pollutants such as pesticides. It provides you with… Full review

SteriPEN Classic

The easiest way to be safe when using unknown water is the SteriPEN! Some friends and myself took a backpacking trip into Denali National Park. Specifically we hiked up the Toklat River crossed the ridge to the west and then returned through what was essentially a swamp. We knew water was going to be a factor on the trip. We had planned on 3 days in and 3 days out with 1 extra day for what ever... So, 7-day trip in the backcountry. The main source of water for the first half was the river. A glacier… Full review

First Need Deluxe Water Purifier XL

We have had this pump for 3 years now. Although it is a little bulky and could be a bit more ergonomically designed, it has been a lifesaver for us. This little purifier gives me peace of mind when we are camping. It is a relatively quick and efficient way to provide safe clean water for drinking. The pumping mechanism is not as ergonomic as I'd like, but it is a small price to pay for health. We use a lightweight collapsible bucket which fits inside the stuff sack with the pump to fetch water from… Full review
